The Newar Cuisine is a unique type of cuisine. Mustard oil and a host of spices, such as cumin, sesame seeds, turmeric, garlic, ginger, methi, bayleaves, cloves, cinnamon, pepper, chili, mustard seeds, vinegar, etc. are used in cooking. The cuisine served in the festivals is considered as the best diet cuisine. The grilled meat over the flames of dried wheat plants makes a delicious and spicy typical newari food called choila. In various occasions people from this tribe cook varieties of food depending on the climate and occasions. Newars use baji(beaten rice) in various occasions. A typical Newari serving consists of the beaten rice, choila, different beans, spiced potatoes, kachila (semi-cooked spiced minced meat) spinach, bara, bitter soups and typically two kinds of liquor. Thwon and aila are the common liquors that Newar make at home.
